摘要
Abstract
As the key part of turbine drive in the electronic parking brake system, the powder metallurgy helical gear was difficult to form because of the non-circular spline structure of inner hole. The structure, performance, material selection, and production process of powder metallurgy helical gear were introduced in this paper. In the results, the well-fluidity powder should be used to fill the helical region of female die. To avoid the fracture of core rod, the pressing machine with non-rotation lower punch is selected. According to the product requirements, the production process is as follows: compacting→ sintering hardening→ tempering→ postprocessing; the compacting and sintering hardening are the key steps. By applying the applicable technology, the high-accuracy, high-strength, and complex-shaped helical gear can be produced, meeting the demand of working condition.The helical gear has been quantity production in stable quality, getting good economic benefits.关键词
